Hi, Spring fans! This week I'm in northern Europe. I went on the Vaadin cruise from Finland to Sweden, gave a talk on a boat, then arrived in Stockholm in time for the amazing JFokus 2026 event where I had the privilege yesterday of doing a deep dive with my pal James Ward on Spring AI and agentic patterns (some of which we also look at in this very roundup).

• Nobody, and I mean nobody, asked. So I put together a video on how to use Spring WS to build SOAP-based services in 2026. Hey, SOAP may be legacy but the legacy endures in a lot of places and there's no reason you can't modernize those systems and services to use Spring Boot 4, GraalVM, and OAuth, as I show in this video.

Hi, Spring fans, to the first installment of This Week in Spring in the new year and, roughly, the fifteenth anniversary edition of this series! I've been writing these blogs since the first week of January of 2011, and I am proud to say that I haven't (so far) missed a single week! I've always published it on Tuesday (with some fuzziness around whose Tuesday, as I tend to bounce around the globe a fair bit). I want to thank, as I always do, Spring cofounder Keith Donald for this wonderful and simple idea. He dropped it in my lap and said to give it a shot, and I've never looked back. He's no…

In this episode, I talk with Mark Thomas, the legendary and highly prolific committer to Apache Tomcat. Happy New Year!
